Participating in the hallowed Throwback Thursday hashtag (#tt) on the social media service, the singer tossed up multiple pictures, some of which featuring her sister. The first was of them as kids, all dressed up and looking at the camera.

It’s the second that’s marginally more interesting. It includes Sisqo, who holds a silver electric guitar, perhaps even crooning while the sisters watch on.

However, the caption notes that the picture “will be deleted tomorrow, and it’s not because I don’t love Sisqo’s awesome guitar.” It’s unclear why she would consider deleting the photo.

She included two additional photos on her Instagram for the throwback spree, including one of her as an even younger child with the caption “sleep talking.”

Solange’s Instagram uploads follow her sister’s similar pictures on her own account yesterday, continuing to act as the only real commentary on what’s transpiring between the two parties since the Met Gala scuffle, during which Solange punched and kicked Jay Z in a leaked elevator video for reasons unknown.
